Findmnt default options

If no specific mount point or device is provided, this command lists all mounted file systems in a nice tree structure by default.

1. $ Findmnt

Findmnt round robin Mode

Findmnt can be used to monitor changes to/proc/self/mountinfo files. In polling mode, you can call the following command:

1. $ Findmnt-p

Or

1. $ Findmnt -- poll

Any changes to the/proc/self/mountinfo file will be automatically updated on the terminal. At first, you won't find any changes in the output in the terminal. If you unplug the USB flash disk and insert it, the changes will appear in the terminal.

The polling stop time can be limited by the -- timeout or -- first-only option.

Timeout Option

This option can be used with -- pool to limit the polling Mode Time. Timeout is measured in milliseconds. After this time expires, findmnt will no longer monitor changes to the/proc/self/mountinfo file.

1. $ Findmnt -- poll -- timeout 6000

First-only option

The first-only option only monitors the first change of the/proc/self/mountinfo file, and then the command exits the polling mode. The first change will appear on the terminal and return to the prompt. Use this option to enter:

1. $ Findmnt -- poll -- first-only
